Our laboratory personnel have many years of experience quantifying biomarkers of oxidative stress in a variety of sample types from human and animal model systems.

We can receive, plasma, serum, urine or tissue samples and are available for consultation at any time to help you determine which biomarker would likely yield the best data based on species, model system, and available sample types.

Our methods include colorimetric, chemiluminescent and ELISA based assays depending on the requested biomarker. Our services are regularly utilized by researchers at leading university, government, pharmaceutical, biotech and contract research organization (CRO) laboratories. Many years of research experience provides us with a healthy respect for the value of biological samples derived from meticulous planning and experimentation. You can rest assured that all samples shipped to our facilities will be cataloged, handled, stored and tested in such a manner as to reduce the chances for sample compromise while increasing the chances for generating the very best data possible.

Volume permitting, samples are tested in sufficient replicates as to provide the possible statistical significance. Once testing is complete, results are meticulously reviewed and scrutinized in order to verify the data for accuracy.
